Verify if TLS 1.2 is enabled

TLS is an abbreviated form of Transport Layer Security Protocol, an industry standard developed with an intention to safeguard the privacy of information communicated over the internet. So, the step first involves in verifying whether TLS is enabled or not by viewing your internet properties. The box adjacent to Use TLS 1.2 should be checked.

For this, press Windows key + R to open the Run dialog box. Type inetcpl.cpl, and hit OK.


Then, in the Internet Properties window, select the Advanced tab and under the Settings list, scroll down until you find Use TLS 1.2. Check the box if it is not checked, click Apply, and close the window.

Try activating Office again.
